PROBLEM TO BE SOLVED: To improve cooling effect of a bearing unit including multiple bearings.SOLUTION: A bearing unit 4 includes multiple bearings 11, 12. The bearing unit 4 cools the multiple bearings 11, 12 by an ambient fluid that has a cryogenic temperature passing through interior parts of the multiple bearings 11, 12. The multiple bearings 11, 12 include: a first bearing 11 disposed at the upstream side in an ambient fluid flow direction; and a second bearing 12 disposed at the downstream side of the first bearing 11. The second bearing 12 includes a bypass passage 19 in which a gas contained in the ambient fluid passes while bypassing the interior part of the second bearing 12.SELECTED DRAWING: Figure 2

    【課題】複数の軸受を備える軸受ユニットの冷却効果を高める。【解決手段】軸受ユニット4は、複数の軸受11,12を備える。軸受ユニット4は、極低温の周囲流体が複数の軸受11,12の内部を通過することにより当該軸受11,12を冷却する。複数の軸受11,12は、周囲流体の流動方向における上流側に配される第一軸受11と、この第一軸受11よりも下流側に配される第二軸受12とを含む。第二軸受12は、周囲流体に含まれる気体が当該第二軸受12の内部を迂回して通過するバイパス流路19を備える。【選択図】図2
